Done for RetroAchievements, which has an achievement for beating Saturn Mode's tracks with Enemy Level set to Very Hard with whatever cars you wish.

For having "Accel B", it really has quite the good speed retention over drifts and even (side) wall hits, likely thanks th the Grip B stat, but your drifts still have to be well placed to make it though, as well as having to do the final drift spot-on to not flounder and lose your spots. This run had a slower first lap (my first lap PB was a 1'41) but clutched on the second half, particularly with a well done final turn.
